SugarSync, which has offered 5GB of free capacity since its founding, today announced it will only offer that as a trial and that all capacity after the trial will have to be paid for.

SugarSync, an online service for data back up, file sync and sharing, Tuesday announced that it will transition to a paid-only service model beginning on February 8, 2014.

Previously, SugarSync offered users 5GB of free capacity. Users can still try the SugarSync service with a 90-day 5GB trial or a 30-day trial with higher capacities of 60GB or more.

SugarSync said the new policy will allow the company to further focus on "updates and improvements that better meet the evolving needs of its consumer and business subscribers."

"There are many companies in this space that are giving away free storage However, most of these companies will not be viable. We are already in a solid financial position and this shift will further strengthen our business," said SugarSync CEO Mike Grossman.

Te change will let SugarSync better serve its "loyal" existing customers through new service enhancements.

SugarSync plans to release redesigned apps and additional features in the coming year.
